Figure 12.
Unsuccessful power-up on STM6601
1.
PB detection on falling edge.
2.
Internal pull-down resistor 300 k
Ω is connected to PSHOLD input during power-up.
3.
PSHOLD signal is ignored during tON_BLANK. When tON_BLANK expires, the level of the PSHOLD signal is not high therefore
the EN signal goes low. Even releasing the PB button after the tON_BLANK will not prevent this.
